ios - 如何从当前选项卡栏加载第二个选项卡栏

Question

我在 tabbarController 中有 TableView Controller 。问题是当我单击 tableView 中的一行时，它不会从现有选项卡栏 Controller 加载第二个选项卡栏 Controller 。

这是我的didSelectRowAt代码:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let storybaord=UIStoryboard(name: "Main", bundle: nil)
        let tabBar=storybaord.instantiateViewController(withIdentifier: "tabBar") as! UITabBarController

        let DVC = tabBar.viewControllers?[0] as! NewsViewController

        let image = sneakersnews[indexPath.row].image
        DVC.getImage = image
        let news = sneakersnews[indexPath.row].news
        DVC.getNews = news
        self.navigationController?.pushViewController(tabBar, animated: true)
    }

Answer 1

您必须将新的 tabBar 作为模式呈现，而不是在您拥有的导航 Controller 内

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let storybaord=UIStoryboard(name: "Main", bundle: nil)
    let tabBar=storybaord.instantiateViewController(withIdentifier: "tabBar") as! UITabBarController

    let DVC = tabBar.viewControllers?[0] as! NewsViewController

    let image = sneakersnews[indexPath.row].image
    DVC.getImage = image
    let news = sneakersnews[indexPath.row].news
    DVC.getNews = news

    present(tabBar, animated: true, completion: nil)
}
